This keyboard has been a game-changer for our commercial access control system .My analysis of this product showed that it is easily programmable and enables seamless integration to existing industrial and scientific systems. The build quality is top-notch making it a durable and reliable solution to use in high-traffic areas. One slight con is that the instructions for programming and setup are a bit dense and may require some expertise to navigate effectively. Overall, a great addition to any commercial door products lineup..
